Adjustable shank supporting traction reduction frame

Abstract

The invention discloses an adjustable shank supporting traction reduction frame which comprises a guide block connected with a bed body and a vertical supporting rod, wherein a fixed arm is arranged on the supporting rod and connected with one end of a connection arm, the other end of the connection arm is connected with one end a suspension arm, the other end of the suspension arm is connected with a shank supporting frame, the connection arm rotates relative to the fixed arm and the suspension arm, and the shank supporting frame is connected with the suspension arm through a universal ball. A guide plate connection groove, a supporting rod threaded hole, a guide block threaded hole, a supporting rod connection hole and a guide rail groove are formed in the guide block, the supporting rod is connected with the supporting rod connection hole, a guide plate and a guide rail are arranged on the bed body, the guide plate is matched with the guide connection groove, and the guide rail is matched with the guide rail groove. The adjustable shank supporting traction reduction frame can assist the fractured shank to achieve intraoperative closed reduction, the shank can be placed, regulated and fixed easily, comfortableness of shank supporting is good, operations for fixing the inner side or the outer side of the shank can be facilitated, fluoroscopy is not influenced, and operation results can be confirmed by obtaining intraoperative standard fluoroscopic images.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an adjustable calf support traction reset frame. Background technique [0002] The current concept of fracture treatment is mainly based on minimally invasive operation and recovery of function. Fractures of the lower leg account for more than half of the fractures of the extremities, and are often associated with soft tissue injuries of varying degrees. In the prior art, closed reduction surgery is the ideal treatment, and intraoperative fluoroscopy is used to determine the effect of reduction and evaluate the curative effect of surgery. In the prior art, the clinical application of the calf support frame is mostly made of metal. The existing defect is that it affects the perspective, the function is mainly the support function, the adjustability is poor, and there is no continuous traction reset function, and most of them rely on manual traction. Exposure to radiatio...

Problems solved by technology

In the prior art, the clinical application of the calf support frame is mostly made of metal. The existing defect is that it affects the perspective, the function is mainly the support function, the adjustability is poor, and there is no continuous traction reset function, and most of them rely on manual traction. exposure to radiation during fluoroscopy

Since some operations need to change the state of knee extension and flexion during the operation, the operation can only be completed, but the structure of the existing technology is simple and cannot meet the requirements for this position change; because it is made of metal materials, it cannot be used in fluoroscopy, but closed reduction The operation needs to determine the operation and reduction effect through effective intraoperative fluoroscopy, which brings inconvenience to the fluoroscopy; in addition, because the operation, especially the closed operation, must be completed before the closed reduction can be performed, the structure of the prior art cannot effectively perform the operation on the legs. The fixation and positioning affect the reduction, thereby affecting the surgical effect
